Diffusion Fixed Gas Detection Device
A diffusion gas detection device works, as the name suggests, on the diffusion principle. The sensor is exposed to the ambient air and will measure the gas by means of the diffusion principle. Diffusion means proportional spread of molecules over the available space (from high concentration to low concentration). This also means that a diffusion gas detection device is only able to measure the concentration of gases at the location where the device is located. Since there is no forced flow of the gas to be measured, this device is not suitable for taking measurements remotely, but they do accurately identify what’s present in a given location.
Pumped Fixed Gas Detection Device
Pumped instruments are equipped with a built-in sampling pump. This means that the device is constantly drawing in gases. A sampling hose may be connected to extend the reach. This means that you can take a measurement from a safe distance so you have an idea of which gases will be present in which concentration before you are exposed to this environment. This allows you to make an appropriate risk analysis and make the right strategy and PPE choices based on the measurement results. By positioning the measuring hose correctly, you can also make a correct measurement at different heights to chart all risks.
